What each ingredient does
- Isinglass
- Sets the liquid into a jelly as it cools.
- Syrup
- Provides the sweetness and the body of the jelly.
- Vanilla pods
- Give the jelly its vanilla flavour as they infuse.
- Maraschino or other liqueur
- Adds aroma and a layer of flavour to the jelly.
The step that matters
Stirring in the isinglass and liqueur when nearly cold. Isinglass sets as it cools, so adding it while the syrup is still hot can weaken its setting power. Waiting until the mixture is nearly cold keeps it ready to gel, and the liqueur stays fresher and more aromatic when not boiled.
